Background

When the gantry crane is installed in a reinforcement processing field of a construction site of a thermal power plant, the installation and removal methods are as follows (fig. 1):

(1) And (2) mounting: when the two supporting legs A are connected with the trolley B and the main beam C through bolts, the distance L2 between the innermost two bolt holes on the main beam C is generally larger than the distance L1 between the innermost two bolt holes of the two supporting legs A, and the distance between the two bolt holes is about 10 cm. If the distance L1 is not adjusted on the ground to enable l1=l2, when the main beam C and the supporting leg a are connected by bolts at high altitude, the connection work of the main beam C and the supporting leg a cannot be successfully completed due to the large difference of the bolt hole distances. In the past, the operator should measure first the bolt hole pitch L2 of two innermost on girder C, and then measure two innermost bolt hole pitches L1 of two landing leg A, then prop up two landing legs A with square timber apron in the middle of two landing leg A, make L1=L2, then set up the shelf with scaffold steel pipe and fix two landing legs A.

(2) Dismantling: in the high altitude, fix two landing legs A with scaffold steel pipe rack, ensure that after demolishing girder C and landing leg A connecting bolt, two landing legs A can not take place the danger of toppling because of rocking to guarantee the life safety at high altitude operating personnel.

The method for using the scaffold steel pipe rack as the stay bar has the following defects: because many projects need to go to the suitable scaffold steel pipe of length of remote job site search and set up, from seeking scaffold steel pipe to the shelf to set up and finish, generally need take about 1 hour, this kind of operation mode not only consumes the physical power of operating personnel, waste time again, landing leg ann tears inefficiency down, influences the construction progress, and the cost is higher. Based on the above, it is especially necessary to design a novel support rod for mounting and dismounting the landing leg of the portal crane.
